Abstract

The invention discloses inorganic lightweight aggregate insulation board maintenance equipment. The inorganic lightweight aggregate insulation board maintenance equipment comprises a box body, an inner cavity is formed in the box body, a storage rack is arranged in the inner cavity and movably connected with the inner wall of the inner cavity, the box body is further provided with an air circulation system, the air circulation system comprises an air outlet assembly, an air suction assembly and a ventilation pipeline, the air outlet assembly communicates with the air suction assembly through the ventilation pipeline, and the air outlet assembly and the air suction assembly communicate with the inner cavity. According to the inorganic lightweight aggregate insulation board maintenance equipment, through the structural arrangement of the maintenance equipment, the maintenance operation in the preparation process can be achieved, the heating rate is accurately controlled while the overallhumidity is guaranteed, meanwhile, rapid dehumidification can be achieved in the later dehumidification operation, and therefore the high-quality insulation board finished product with the good maintenance effect and the low water content can be obtained.

Description

technical field [0001] The invention relates to the technical field of thermal insulation boards, in particular to maintenance equipment for inorganic light aggregate thermal insulation boards. Background technique [0002] Insulation boards are generally made of polystyrene resin as raw material plus other raw and auxiliary materials and polymers. After heating and mixing, catalysts are injected at the same time, and then extruded to form rigid foam plastic boards. It has moisture-proof and waterproof properties. It can reduce the thickness of the building's outer envelope, thereby increasing the indoor usable area. [0003] The current insulation boards generally have cement components, and maintenance is required to ensure the performance of the cement components in the fireproof boards, but none of the existing maintenance equipment can achieve a better maintenance effect. [0004] In view of the above defects, the inventor of the present invention has finally obtained ...
